- Аннотация: To reduce membrane fouling and increase separation performance during the separation of butanol fromfermentation broth, novel membrane materials based on copolymers of polydecylmethylsiloxane and siloxanescontaining fluoroalkyl acrylate side groups (with 3–6 fluorine atoms) were synthesized and investigated for thefirst time in the pervaporation process. The introduction of fluorine-containing groups into polysiloxanes resultedin a sharp decrease in the surface tension to a near constant value of 16–17 mJ/m2, which in turn led to thehydrophobization of the polymer film’s surface. Fluoro-containing polymers demonstrated higher sorption capacities for butanol, acetone, and ethanol compared to 0F. During the separation of a model ABE fermentationmixture using composite fluorosiloxanes based membranes, the partial fluxes of target components wereapproximately 1.5 times higher than those observed for the virgin polydecylmethylsiloxane membrane. Thebutanol/water separation factor increased with fluorine concentration in the membrane from 43.7 to 49.3.Membranes based on fluorosiloxanes demonstrated the highest resistance to fouling during the contact with realdeactivated ABE-fermentation broth: the poly(pentafluoropropylacrylate/decyl)methylsiloxane based membranemaintained a steady total permeate flux of 3.4 kg μm/(m2⋅h) over 700 h of separation.
